Abstract We present a set of low and intermediate mass star yields
based on a modeling of the TP-AGB phase which affects the production
of nitrogen and carbon. These yields are evaluated by using them in a
Galaxy Chemical Evolution model, with which we analyze the evolution
of carbon abundances. By comparing the results with those obtained
with other yield sets, and with a large amount of observational data,
we conclude that the model using these yields combined with those from
Woosley & Weaver (1995) for massive stars properly reproduce all the data. The
model reproduces well the increase of C/O with increasing O/H abundances. Since these massive star yields do not include winds, it
implies that these stellar winds might have a smoother dependence on
metallicity than usually assumed and that a significant quantity of
carbon proceeds from LIM stars.
